HERBERT L. BOLT, OF SMUGGLER, COLORADO.

ROTARY-TOOL HOLDER.

Application filed December 17, 1915. Serial No. 67,389.

To all y'uf/0m t may Concern Be it known that l, HERBERT L. HOLT, a citizen of the United States, residing at Smuggler, coun-ty of San Miguel, and State of Colorado, have invented certain new and useful Improvements in Rotary-Tool Holders; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for washing and drying utensils such as dishes and the like, and my object is to presen-t a portable device of this character having a brush mounted upon one extremity and its opposite extremity adapted to be con nected with suitable means for rotating said brush, whereby both the aforesaid washing and drying functions may be performed.

Another object of my invent-ion is to so construct the device that the elements which compose the same may be readily detached from each other for cleaning or other purposes.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing Figure 1 -is a longitudinal sectional view of my improved device with the parts assembled. Fig. 2 is a longitudinal sectional View of the device with the end pieces or caps detached.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a shaft having spaced shoulders 6 and 7 formed thereon, the said shaft adapted to be journaled within a shell or casing 8 composed of hard rubber or other suitable material. This shell 8 is composed of a body part 9 and detachable end pieces or caps 10 and 12. The extremities of the said body portion of the shell are interiorly threaded at 13 to receive bearings 141 and 15 which are exteriorly threaded for this purpose, said bearings alsol having openings or recesses 16 formed in their outer ends, whereby they may be readily detached from the body portion 9 of the shell by means of a Spanner wrench.

The shaft 5 is journaled in these bearings and the inner ends of the latter' are adapted to respectively engage the shoulders 6 and 7 formed upon the said shaft.v The bearings extend beyond the opposite extremities of the body portion 9 `for approximately half their length and upon these extensions are screwed the caps 10 and`12 respectively, which are yinteriorly threaded as shown at 17. The opposite extremities of the shaft 5 project beyond the ends of the shell 8 through pcrforations 18 Vand 19 formed in the respective caps and the forward extremity of the said shaft is reduced and formed rectangularin shape as shown at 2O whilev its rear extremity is exteriorly threaded as illustrated at 21. Upon the said reduced extremity 2O of the shaft is mounted a brush holder 22 provided with a sleeve 23 whose interior is shaped to correspond with the said reduced extremity of the shaft 5. The inner end of the sleeve will abut against a shoulder 24 formed adjacent the rectangular portion of the shaft, and the holder 22 will be secured in place by means of a thumb-screw 25 mounted in the sleeve 23 and whose inner extremity is adapted to engage one face of the said rectangular portion 20. lThe outer extremity of the brush holder is reduced and exteriorly threaded as shown at 26, and upon which threaded portion is screwed a brush 27. The brush illustrated in F ig. 1 of the drawing `is only one of many types which may be employed, the selection of the brush depending upon the character of the work to be performed.

Also, the connection between the brush and the forward extremity of the shaft may be varied as circumstances may require, the

construction disclosed upon the drawing` merely being a convenient manner for formingthe said connection. Y

In employing the above described apparatus the rear threaded extremity 21 of the shaft 5 is connected with a flexible shaft (not shown) adapted to be rotated by an electric mot0ror other suitable means, whereby the shaft 5 and the brush 27 will have a corresponding movement imparted thereto. During the operation ofthis device the shell or casing of the latter is gripped in the hand of the user, whereby the apparatus is portable, and utensils of all descriptions may be washed and dried. f

Attention is called to the fact that the device can be readily taken apart for cleaning purposes or for the replacing of any part which may become worn or injured.

Having thus described my invention7 what I claim is l. An article of the class described comprising a cylindrical casing composed of a body portion and end pieces, a bearing located within each end of the said casing, the body portion of the latter being detachably connected with lboth bearings and the end pieces being detachably connected with the respective bearings, a shaft journaled within said bearings and having shoulders formed thereon, which are adapted to abut against the inner ends of said bearings, the outer ends of the bearings having spaced recesses formed therein and the extremities of the shaft projecting beyond the opposite ends of the casing through openings formed in said end pieces, one extremity of said shaft adapted to support a tool while its other extremity is adapted to be connected with means for rotating the same.

2. An article of the class described comprising a cylindrical casing composed of a body portion and end pieces, a bearing located within each end of the said casing,

one extremity of said shaft adapted to support a tool while its other extremity is adapted to be connected with means for rotating the same.

3. An article of the class described comprising a casing composed of a body portion and end pieces, a bearing` screwed into each extremity of the body portion and the end pieces adapted to be screwed upon the respective bearings, a shaft journaled within said bearings, one extremity of the said shaft adapted to support a tool while its other extremity is adapted to be connected with means for rotating the same. Y

In testimony whereof affix my signature in presence of two witnesses.
